Hazelnuting 

When you pull someones ear hard as a joke

Imogen was being annoying so I hazelnuted her
Hazelnuting is not painful so suck it up

Hazelnutting 

When you dip your balls in Nutella (or any hazelnut butter), then proceed to T-bag your significant other. (could also be a prank)

My kinky/hungry girl friend wanted to try something new, so we bought some Nutella and I ended up hazelnutting her last night.
